IPC: G06F1/025
Filed: 2002-03-21
Abstract: A pulse-width modulation technique uses a counter load value that alternates between a duty-cycle defining value and its complement. In one embodiment, a pulse-width modulated signal is produced as a function of a control signal used to reload the counter in response to the counter reaching an overflow threshold value. This approach includes storing the counter load value and counting relative to a logic circuit output value which corresponds to either the load value or its complement. The counting is reinitiated using the logic circuit output in response to the counter reaching an overflow threshold value. A specific example application of the above type of PWM approach is directed to implementation in otherwise conventional up/down digital counters such as exists in 80C51-type microcontrollers.
